Timothy, to whom this epistle is written, was eminent for his early piety and acquaintance with the sacred Scriptures; his mother was a Jewess, and his father a Greek, which was the reason why he was not circumcised in his infancy. Mention is made in the second epistle to him of his mother Eunice, and grandmother Lois, as believers, and of his knowledge of the Scriptures from a child: this excellent person the apostle meeting with at Lystra, and having a good report of him from the brethren there, he chose him to be his companion in his travels, and to assist him in the spread of the Gospel; and knowing that it would be very disagreeable to the Jews to hear the word of God from the lips of an uncircumcised person, he took him and circumcised him, becoming all things to all, that he might gain some. This being done, he went along with him into several parts, and he made great use of him, in preaching the word, planting churches, and writing epistles; he sent him to various places with messages from him, to Corinth, Philippi, and Thessalonica; and now had left him at Ephesus, where he besought him to abide for a while; for that he was the bishop, pastor, or overseer of that church is not likely, since his residence here was not constant, and was afterwards called away from hence by the apostle, who desired his stay there, under whom, and by whose directions, he acted while there; and seeing that this church had elders, bishops, or overseers, whom the Holy Ghost had set over them, whom the apostle called to him at Miletus, and gave them some advice and instructions. The design of Timothy's continuance there was to check growing errors and heresies, and to take care of, and preserve the discipline of God's house; and to charge him with these things was the design of this epistle; in which he teaches him how to behave himself in the church of God, by taking heed to his doctrine and conversation; and gives rules relating to the qualifications of bishops and deacons, and to the care of widows, and with regard to church censures, and the becoming walk and conversation of all sorts of persons of every office, age, sex, rank, and order. This epistle is thought to be written about the year 55.
